How do I select a specific instance?

I would have the source instance create a packet object (and possibly record the source in an instance variable in the packet object), then have a separate event on packet created pick the proper destination instance by comparing instance variables ("Name") and apply whatever movement you have implemented based on the picked instance's coordinates.

How do I select the source though? There are two instances of servers, I want the Alice server to create a packet and bullet it over to the Bob server.

Pick by comparison

Pick the individual instances of an object type that meet a comparison. For example, it is possible to pick all instances where Object.X * 2 is less than Object.Y + 100, which is not possible with either the Compare X or Compare Y conditions.

So in your case it would be Pick "Server" object by comparison self.Name="Alice" -> Spawn Packet

Then

On Packet created

Pick "Server" object by comparison self.Name="Bob" -> Set Packet Destination to Server.X, Server.Y

Thanks, where is Self used though?

I've got a sample app here:

All I'm trying to get it to do is fire a projectile from left to right when 1 is pressed and right to left when 2 is pressed.

I'm definitely missing some basic concept here.

Here you go. Changed the approach slightly, since I realized if you use "On Created", the target hasn't been set yet. Instead, I used a sub event with the "Pick all" system condition to reset the picked instances, then narrowed it down again from there.

Also you might notice I used a different condition than the System-Pick by Comparison. In the object you can also compare instance variable. I'm actually not sure what the differences between these two methods of picking are.

The other thing I changed was using the Tween behavior instead of Bullet, since you have a clear start and end point, Tween is probably more suitable.

Sorry if my answer earlier was confusing, I can make more sense with an example to work with ;)

Thanks oosyrag,

Still don't fully understand, but you've given me some things to work with there. Very much appreciated!

Why are the projectiles being created above the "Muzzle" image point though?

That was it, thanks oosyrag
